uploading images to a server

kikilahooch · August 21, 2006

I'm trying to upload images to a server using code that was given in a tutorial on this site: [url=http://www.phpfreaks.com/tutorials/85/0.php]http://www.phpfreaks.com/tutorials/85/0.php[/url]

I'm very new to php so I am not sure if followed it correctly. I basically copied and pasted it all and modified the path where images are stored and the log directory and saved it as Upload_Class.php

[code] <?php

class Upload_Files {

var $temp_file_name;

}
?>
[/code]

Then I called the class using a using a file called test_upload.php

[code]

<?php
//SECTION #1

include("Upload_Class.php");

$upload_class = new Upload_File; //line 7
$upload_class->temp_file_name = trim($_FILES['upload']['tmp_name']);
$upload_class->file_name = trim(strtolower($_FILES['upload']['name']));
$upload_class->upload_dir = "uploads/";
$upload_class->upload_log_dir = "uploads/upload_logs/";
$upload_class->max_file_size = 524288;
$upload_class->banned_array = array("");
$upload_class->ext_array = array(".jpg",".gif",".jpeg",".png");

//SECTION #2

$upload_file = $upload_class->upload_file_with_no_validation();

?> [/code]

When I try to upload an image then I get the error message:

Fatal error: Cannot instantiate non-existent class: upload_file in /home/c/ciaracousins/public_html/test_upload.php on line 7

Would really appreciate if someone could point out where I am going wrong

ToonMariner · August 21, 2006

make sure the path to the file in your include statment is correct

onlyican · August 21, 2006

use require not include
If the file is not including, require will throw an error

kikilahooch · August 21, 2006

Thanks! realised what I had done, had misspelt one of the class names. Now though when I go to upload it just brings me from my fileupload.html page, to a blank page (test_upload.php), it doesnt even give me any errors and the file is not uploading. I changed the code for calling the class to this then to see if it would tell me why its not uploading but this too just brings me to a blank page (test_upload.php) and doesnt work.

[code]
<?php

include("Upload_Class.php");
$upload_class = new Upload_Files;
$upload_class->temp_file_name = trim($_FILES['upload']['tmp_name']);
$upload_class->file_name = trim(strtolower($_FILES['upload']['name']));
$upload_class->upload_dir = "clothes/";
$upload_class->upload_log_dir = "log_dir/";
$upload_class->max_file_size = 5242880;
$upload_class->banned_array = array("");
$upload_class->ext_array = array(".zip",".rar",".ace",".tar");

$valid_ext = $upload_class->validate_extension();
$valid_size = $upload_class->validate_size();
$valid_user = $upload_class->validate_user();
$max_size = $upload_class->get_max_size();
$file_size = $upload_class->get_file_size();
$file_exists = $upload_class->existing_file();

if (!$valid_ext) {
$result = "The file extension is invalid, please try again!";
}
elseif (!$valid_size) {
$result = "The file size is invalid, please try again! The maximum file size is: $max_size and your file was: $file_size";
}
elseif (!$valid_user) {
$result = "You have been banned from uploading to this server.";
}
elseif ($file_exists) {
$result = "This file already exists on the server, please try again.";
} else {
$upload_file = $upload_class->upload_file_with_validation();
if (!$upload_file) {
$result = "Your file could not be uploaded!";
} else {
$result = "Your file has been successfully uploaded to the server.";
}
}
?> [/code]

Any idea why its doing this??

Here is the code to my fileupload.html page as well if it helps

[code]<html>
<head>
<title>A simple file upload form</title>
</head>
<body>
<form action="test_upload.php" enctype="multipart/form-data" method="POST">
<input type="hidden" name="MAX_FILE_SIZE" value="51200">
<p><strong>File to Upload:</strong> <input type="file" name="fileupload"></p>
<p><input type="submit" value="upload!"></p>
</form>
</body>
</html>
[/code]

ToonMariner · August 21, 2006

yep...

in the script you look for $_FILES['upload'] and in the form you have called it name="fileupload"

so change name="fileuplaoad" to just name="upload"

kikilahooch · August 21, 2006

Thanks ToonMariner, I changed the line to

<p><strong>File to Upload:</strong> <input type="file" name="upload"></p>

Its still not working though, It keeps going to a blank test_upload.php page. It goes straight to the page as well, so its not even trying to upload anything. Any other advice??

onlyican · August 21, 2006

It will go to test_upload straight away, as the form is being submitted

You are not echoing anything

echo $result;

kikilahooch · August 21, 2006

Thanks onlyican! Now it is telling me why it wont upload. It keeps saying :

The file size is invalid, please try again! The maximum file size is: 5 MB and your file was: 1.35 KB

Can you point out where I have gone wrong with this?? Heres the validate size code

[code]
function validate_size() {
$temp_file_name = trim($this->temp_file_name);
$max_file_size = trim($this->max_file_size);

if (!$temp_file_name) {
$size = filesize($temp_file_name);
if ($size > $max_file_size) {
return false;
} else {
return true;
}
} else {
return false;
}
} [/code]

I'm really new to this and got the code from a website so sorry if I'm missing really obvious stuff here!

ToonMariner · August 21, 2006

if ([color=red]![/color]$temp_file_name) {

get rid of the '!'

onlyican · August 21, 2006

[quote author=ToonMariner link=topic=105044.msg419418#msg419418 date=1156167641]
if ([color=red]![/color]$temp_file_name) {

get rid of the '!'

[/quote]

The ! is saying if NOT true

kikilahooch · August 21, 2006

Thanks! Ok now it is saying "This file already exists on the server, please try again" but the file is new and is not on the server. I removed all code then that checks to see if the file already exists because its not really important in my case but then it just says:

"Your file could not be uploaded!"

Can you see anything that is stopping it from uploading??

onlyican · August 21, 2006

your CHMOD set to 777?

kikilahooch · August 21, 2006

I dont even know what CHMOD is! Is this in my code somewhere?? I cant see it

onlyican · August 21, 2006

ok ok
How do you upload the files to your website?
Right click on the folder where the uploaded files go
Choose Properties / File Attributes / Settings (Something)
and you should be able to change the Attributes, the CHMOD
Try 755, if it fails, try 777, if it fails, let us know

kikilahooch · August 21, 2006

Ok I did that, but I am using a hosting site and when I choose properties it just brings up one page (common), there are no tabs to choose file attributes, but on that page it says "permission", here it has:

owner: R W X Set UID //with check boxes beside each of them, all the R,W,X's are checked except 2 of the W's, when I put 0777 these were also checked
Group: R W X Set GID // and the Set UID,GID and sticky bit are unchecked
Others: R W X Sticky bit

Octal: 0755

I tried changing the octal to 0777 if that is the same as what you are talking about but there was no change

onlyican · August 21, 2006

ok
That is what I am talking about
You are changing the folder where the files will be uploaded to?

kikilahooch · August 21, 2006

Yes, my files are being uploaded to a folder called clothes, so that is the folder that I right clicked on...was that right?

onlyican · August 21, 2006

yep

kikilahooch · August 21, 2006

Any other ideas why it mightnt be working?? Or even any other method for uploading files?
